Bankruptcy-focused investment firm Cherokee Acquisitions has started offering “put options” to crypto investors to protect their funds on crypto exchanges Binance, Coinbase and Kraken in the event of a bankruptcy, CoinDesk learned Wednesday from the company.

The put options will protect account holders’ deposits on the listed exchanges, paying back 100% of the assets in the account if the exchange files for bankruptcy protection within the contract period.

The monthly fees of the options are 0.25% to 0.35% for funds on Coinbase, 0.35% to 0.45% for Kraken and 0.45% to 0.55% for Binance Holdings Ltd, the firm said in an email to investors reviewed by CoinDesk.
